Israel Folau will reveal why he turned his back on a return to league to play Super Rugby when he announces his one-year deal with the NSW Waratahs on Tuesday.

Angered by the tone of some of the criticism he has endured since advising Parramatta Eels coach Ricky Stuart of his decision last Friday, Folau has indicated that he plans to tell his side of the story.

''Everyone is entitled to their opinions but I'll speak the truth when it's my time," he tweeted.

Melbourne Rebels coach Damien Hill has questioned how the Waratahs could fit Folau in under the new $4.5 million Super Rugby salary cap at such late notice.
